Application october 17,1932. serial Natsazav Y 3 Claims.` (.Cl. 4571-1-99) My invention relates generally to'mirror attachments and particularly to an attachmentof the nature of a dental mirror to be incorporated in an ordinary mirror, for the purpose of en- Y abling a dental patient to View any of his teeth in the mirror.

It is an important object of my invention to provide means for assemblinga dental mirror to anl ordinary irror so that the dental mirror will not impair the usefulness of the ordinary mirror in its ordinary functions.

It is also an important object oi' my inventionY to incorporate a dental mirror in an ordinary mirror in a compact and efficient arrangement Whereby a fined relation may be adjustably establishedV between the dental mirror and thn ordinary miny ror, so that the dental mirror may be placed within the mouth or" a patient and reflect appearances therein to the hand mirror where they may be seen by the patient.

Other objects and advantages lof my invention will be apparent from a reading of the following description of the drawing, wherein for purposes of illustration I have shown a preferred embodiment of the invention.

In th-e drawingzn Figure 1 is a plan View of an embodiment of the invention. Y

Figure 2 is asimilar View enlarged of the'handle portion of the embodiment.

Figure 3 is a longitudinal sectional view through Figure 2the section being taken on line 3 3 of Figure 2. j

Figure 4 is a transverse sectional view therethrough the section being taken on line 4 4 of Figure 2.

Referring in detail to the drawing, the numeral 5 generally designates a suitable form of hand mirror possessing the handle 6 which may bel circularly enlarged as indicated at 7 at its outer end.

Extending longitudinally in the` handle portion 6 is a recess S which extends from a point 9 near the mirror frame l0 to and into thecircularly enlarged end portion 7 of the handle. Between the mirror frame l0 and the end portion 9 of the recess 8 is another recess 11 in which is disposed a hinge member generally designated 12including a hinge pin 13 on which-is swingably connected a bar 14 by means of which the adjustable dental mirror 15 is adjustably connected to the hand l mirror 5.V The .dental mirror 15 is adapted toA be Y nested in the recess 8 so that it is either flush or below the edges of the handle portion 6, so'as not to interfere with the free use of the hand mirror tion 15 is exteriorly screw-threaded as indicated at 21 and receives thereon the threaded adjusting or collar 22. The threaded portion 21 is split as indicated by the numeral 23 in'Figure 4 and tapered so that when the ring v22 is turned PA'rE-TYLOFIC t 'thereon in one direction, the rod 17 whichjis telescoped into the tubular handle portion 16 so as tobe longitudinally adjustable thereof may be clamped in adjusted extended position.

On the end of the rod` 17 exterior of the tubular handle portion 16 is a male member l24 of a ball and socket swivel joint generally designatedr25 of which the female member 26 is con-y nected by a collar 27 which is threaded to receive the handle portion 28 of va conventional dental o,

mirror 29.' lA suitable circular or other properly formed expanded portion of the recess S'extends into the circularly enlarged end portion '7 of thev handle and accommodates the dental mirror in the 'vnush disposition shown in the drawing. This circular enlargement of the lrecess 8 is indicated by the numeralS as seen in Figure 2.

When the combination4 is desired to be used by a patient, the dental mirror structure is swung relatively to the hand mirror structure until a desired relative angularity is achieved bef tween the-.dental mirror 29 and the hand mirror 5, so that an image of a tooth or other portion of the'interior of the mouth of the patient incident upon the dental mirror vwill be reiiected by the dental mirror to and upon the hand mirror, which is maintained in a clearly visible relation by the patient.v Y' I Y i It will be observed that the dental mirror may be extended, changed as to angularity in an unlimited number of planes, `and rotated on its axis to assume any desired position. It is obvious that the patient may adjust the Vdental mirror within his mouth so as to direct the same at any tooth orother formation, andrmay then look in the hand mirror to obtain a clear and unobstruct` ed View of the part being examined. Y It isthoughtfrozn'the foregoing description the hand mirror, and a recess in the handle member of the hand mirror for nesting the auxiliary mirror.

2. A dental accessory comprising a large mirror,` a handle member on the large mirror, an auxiliary mirror connected to the handle member and adjustable with respect to the hand mirror, and a recess in the handle member of the hand mirror for nesting the auxiliary mirror when the same is not in use, said auxiliary mirror being adapted to be placed by a patient into his mouth and adjusted so as to reflect an image of a part desired to be examined so as to appear in the hand mirror.

3. A dental accessory comprising a large mirror, a. handle member on the large mirror, an auxiliary mirror, a'handle connectedktherewith, s. rod. a ball and socket connection between the rod and the handle of the auxiliary mirror, a sleeve in which the rod is adjustably mounted lfor sliding movement, a second rod hingedly connected to the handle member of the large mirror adjacent; the inner end of said handle member and a ball and socket connection between the sleeve and said second rod.
